Özet:

 

In this paper, catch per unit efforts (CPUEs) of mono- and multi-filament trammel nets were comparatively investigated on capture of fish species in Lake Beyşehir. To determine the CPUEs of the net types fishing experiments were conducted by the nets with mesh sizes of 28, 40, 50 and 60 mm between April and December 1998.  The mean CPUE was calculated to be 22.39 and 11.12 g/m for mono- and multi-filament net types. According to these results the mean CPUE of monofilament nets was 2.02 fold higher than those of multifilament nets. Tench (Tinca tinca L., 1758) constituted about 80% of the CPUEs of the net types. These species were followed by carp (Cyprinus carpio L., 1758), pikeperch (Stizostedion lucioperca (L., 1758)) and chub (Leuciscus lepidus anatolicus Bogutskaya, 1997) for monofilament net type. The rate of pikeperch in the multifilament net type was higher than carp. The results of the study showed that both the CPUEs of the net types and difference between the CPUEs were gradually decreased from Spring to Autumn. 	 	 		 .
